Answer:
Step-by-step explanation:
Given that a curve in polar coordinates is given by:
r=9+3cosθ
a) At point P, we have

Substitute to get

b) Cartesian coordinate is

c) At the origin r =0
when r =0
we have

Since cos cannot take values as -3 it doe snot pass through origin.
Answer: second Congress
Step-by-step explanation:
Short and sweet
Answer:
Option B is the correct choice.
Step-by-step explanation:
The graph is attached below.
We have to find the
intercept meaning the value of the point on
when 
So we will put the value of zero
instead of
in our given equation.
So here we have solved it algebraically.

Putting 


Multiplying
both sides.

Adding
both sides.

Dividing with
both sides.

So the x-intercept of the given equation is
which can be written as
in terms of coordinates.
Option B
is the correct choice.
